Are these guys serious? I couldn’t see anywhere in the net for such a huge requirement for fiber cables in Germany.
60,000 km cables a year! What is the reference for this news?

Good attempt. You need to update the article by adding the latest applications of fiber optics such as 5G and Data center/hyperscale etc.

And a few diagrams helps people to understand quickly. explanation of fiber optics without pictures is really boring, sorry to say.

Good and informative summary of optical fiber communication. This article will be particularly helpful to students pursuing their career in Fiber optics. Thanks Cindy!
